储存环境对鸡蛋壳表面3种沙门氏菌存活与迁移的影响
Effects of Storage Conditions on Survival and Migration of Three Kinds of Salmonella on Eggshell
摘要
Abstract
In order to study the effects of storage conditions on survival and migration of three kinds of Salmonella,S.enteritidis,S.typhimurium and S.pullorum were artificially contaminated on eggshell.Different environment temperatures (4,25 and 37 ℃) and relative humidity (50% and 90%) were seted,and the number of Salmonellas on the surface of eggshell and egg contents were counted and detected on various time points.The results showed that 4 ℃ obviously reduced the number of three kinds of Salmonellas.At 50% RH,the number of three kinds of Salmonellas were reduced on eggshell surface at 25 and 37 ℃ environment.At 90% RH,despite the individual time points,the number of S.enteritidis and S.typhimurium presented downward trend at 25 ℃.And at the 37 ℃,the number of S.pullorum rapidly reduced,and the number of S.enteritidis and S.typhimurium firstly decreased and then increased,and finally maintained at the level of inoculated magnitude.The results of egg content detection showed that S.enteritidis and S.typhimurium were more likely to be detected in high temperature and high humidity environment,while S.pullorum was not detected in all kinds of experimental environment.The results suggested that low temperature and low humidity reduced Salmonellas survival on eggshell and inhibited it migration into the egg,and high temperature and high humidity could promote Salmonellas proliferation,increase the risk of its penetration into egg.There were some differences in the survival on eggshell and invasion between the different serotypes Salmonellas.关键词
